True or false. the hawthorne studies concluded that productivity at work seldom changed, but an employee's attitude could show significant improvement if he/she were given the opportunity to think critically at work.

True

Explanation:  

Productivity seldom changes in a work environment, and it also depends on the structure of the organization or work environment. most work environment enables employee's to think critically which depends on the nature of the job, some employees think of their KPIs, some think on their tasks and others think of the work pressure, all this contribute to the improvement of the employee on the job. This still proves Hawthorne studies that productivity seldom changes in a work environment because everyone is involved in the thinking process.
